IMPROVEMENT IN RooFiNe-TJLE MAcHlNEs.

Specilication forming part of Letters VPatent No. 188,291, dated March 13,1877; application filed 'August 5, 1876.

To-all y'whom it may soncem:

Be it known that I,f-J AooB GREE NAWALT, of Pittsburg, Pennsylvania, have invented a new and useful -Improvement in Roofing-Tile Machinery, which improvement is fully set forth in the following specification, reference being had to the accompanying drawing.

Similar letters of reference indicate corresponding parts.

The object of my invention is the construction and operation of va machine for forming and molding roofing-tile for houses and other buildings and consists in a system of devices working automatically with each other for the forming of tiles of the desired form, and carrying the same to a kiln for burning.

1n order to enable others skilled in the art to which this appertains to make and operate my invention, I will now proceed to describe the same, reference being had to the accompanying drawing, in which- Figure 1 is a perspective view of my tilemachine. Fig. 2 is a plan view of the reverse side thereof, representing, by dotted lines, the pinion-Wheel fr and cog-wheel S in the rear of the drum b and pulley C. Fig.3 is a Vertical longitudinal section. Fig. 4 represents the die for forming the top part of the tile, and Fig. 5 the die for forming the under part of the same.

A represents the frame-work of my machine, constructed of any suitable material. Attached to the frame-work by journals is the drivingshaft B,'counter-shaft C', and cylinder-shaft D. Attached to the shaft B is the driving-pulley b. The power is communicated to the machine by a belt from an engine, or other motive power, operating. the driving-pulley b. Attached also to the shaft B is a cog pinion-Wheel, fr,

' which engages with the cog-wheel S on the shaft C', communic'ating a rotary motion to the shaft C'. Secured to the shaft lC' are the pulleys O and gear-wheel S. By means of the wrists 02 c2 and the beams e e, a rcciprocating motion is communicated to the levers ff, the ends of the beams e e are attached to the levers f f by wrists f3 fa. The levers f f are suitably pivoted at f2. Attached to the end of the levers f is a suitable frame-work, g, to which the plunging part of the dies k s hl h h is secured. To the shaft D is cylinder t'.

are made of steel or chilled iron of suitable size and Shape on. the outside surface, to be bolted or secured in proper manner to the Openings J J' are made in the top ot' the dies J J of lozenge or diamond shape, of

- suitable depth to receive the clay to be formed.

The bottom surface of the diesJ J is made level, except a sunken groove, hl, about yone-eighth of an inch deep and about one-fourth of an inch wide, of angular shape, and extending from side to side of the die,-and near the top h? of the same. Working in conjunction withthe dies J is the follower or plunger die h, operated by the levers f. The dies h are made of hardened Steel or chilled iron, diamond or lozenge shaped, of a suitable thickness, and are secured to the frame-work g. The lower surfaces of the dies h h form an inclined plane from the point k to the points k' la' k', of about the depth of three-eighths of an inch below the level of the point k. The parts ll are sunken in the same direction about one-half the depth of the point k. 'The parts a' are made level at the same depth of the point k. Upon the level part of the part n is a raised ridge, m, of about one-eighth of an inch high, and of about one-fourth of an inch wide, of angular shape, running from side to side of the die.

The peculiar shape of these dies, ridges,

grooves, &c., is necessary in the construction and manufacture of tiles, such as are fully deseribed in my application for a patent on roofing-tiles filed in the United States Patent Oflice on the 28th day of July, A. D. 1876.

`I will now proceed to describe the operation of my machine. When the driving-pulley is set in motion the pinion upon the shaft B of the same engages with the cog-wheel of the shaft O', imparting a rotary motion to the shaft, which,

'in turn, imparts a reciprocating motion to the levers f f by means of the wrists 02 02, beams ee, and wrists faf3, and pivotsfzfz, and at the same time, by the motion of the shaft C', the cogs of the wheel r en gage with the cogs of' the Wheel S upon the cylindershaft d, there being six 4ated by a pulley, na, beneath the frame A,

cogs to the wheel on the oylinder-shaft and two of the same size andwithin the same space on the Wheel r. It will be seen that the shaft O' makes a full revolution, the cylinder Will make but one-third of a turn; and also that, the lever f being operated by a full turn of the shaft C', the cylinder is allowed to come at rest at the proper position, While the lever f moves up to the same, compressing the dies and molding the tile, allowing the lever to move back out of the way of the cylinder-rwhile the same is moved forward for the next operation. l

The machine is so adjusted that While one set of tiles is being molded upon one of the three sides of the cylinder, the empty dies are being filled by an endless belt or other suitable mechanism, and the molded tiles are being discharged uponan e'ndless belt, na, operwhen it is carried to any point desired for burning. i

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-- 1. The cylnder gear-Wheels r and S, levers f, beams e, wrists o' and fa, pvot sf, and Wheel O, substantially 'afs 'described ali shown.

2. The diamond-shapeddies J and h, working in conjunctiou with 'each other, having the planes inclined from the point la to the points k' k' k', depressions l l, level parts n, rid'ge m, and sunken groove hi, as described and shown substantially, and for the purpose set forth.

3. rhe combination of the'triangular cylinder fi, dies h and J, gear-wheels r and S, pulley C, beams e, levers f, Wristsf3 and 02, pivots fz, pnlley ni, and endless belt ns, all combined and arranged substantially as and for; the

purpose set forth.

4. In a roofing-tile machine, the diamondshaped dies, having the bottoms inclined from the point k to the points k' k' k' and level part n, for making a tile thinner at its upper edge, and rabbeted at its lower edge; substantially as described and shown.`
